ABSTRACT
ABSTRACT: As a special equipment, the crane is widely used in building, metallurgy, petrochemical fields and other fields. The failure degree and risk of crane parts has a significant influence on crane operation performance. According to the typical failure modes and working characteristics of crane parts, a method that using the reliability theory and coefficient correction method to compute the failure probability and then combining the risk matrix method to assess risk of crane parts is proposed. In this paper, a mathematical model of failure probability is built, and the influence weights of failure parts are determined by the Analytic Hierarchy Process. The failure correction coefficient of crane parts is calculated. And then, the process of the failure probability computation and risk assessment for the crane parts is given. Took a typical crane part as an example, the results indicated that the method can solve the problem of computing failure probability and assessing the risk of common crane parts, and it provides the basis and reference for the risk assessment of crane.
